  summary: "Computes inverse hyperbolic cosine of x element-wise."
  description: <<END
Given an input tensor, the function computes inverse hyperbolic cosine of every element.
Input range is `[1, inf]`. It returns `nan` if the input lies outside the range.

```python
x = tf.constant([-2, -0.5, 1, 1.2, 200, 10000, float("inf")])
tf.math.acosh(x) ==> [nan nan 0. 0.62236255 5.9914584 9.903487 inf]
```
